CRIU generates a set of <code>stats-<type></code> files that contain statistics about how dump/restore went.
== Dump/Pre-dump stats ==
These are in <code>stats-dump</code> file. Fields are:
;<code>freezing_time</code>
:Time it took criu to freeze the process tree
;<code>frozen_time</code>
:Time tasks were in frozen state
;<code>memdump_time</code>
:Time criu spent grabbing required pages out of processes. This time does ''not'' include the next time
;<code>memwrite_time</code>
:Time criu spend transferring memory pages into image files (locally or on page-server)
All the above times are in microseconds.
;<code>pages_scanned</code>
:The number of pages criu looked at to decide whether or not to dump them
;<code>pages_skipped_parent</code>
:The number of pages criu skipped due to they were found in parent images (read about [[memory changes tracking]])
;<code>pages_written</code>
:The total number of pages criu put into image files
